Yes we did land on the moon and we haven't been back because no one with a space program is making that a priority mainly for financial reasons. Moon landing deniers are no different than any other conspiracy theorist.... wackos.

From what we currently know of the moon it has plenty of value to offer. The biggest thing travel to the moon offers is practice/a testing ground for technology that would allow us to gather resources from and explore space to gain more knowledge. We could build our first off world outpost on the moon and fully explore the resources the moon has to offer us and ways to efficiently and effectively get them back to Earth... we can also use it as a jumping off point for mining asteroids or even for a trip to Mars. If we ever want to get off this rock we call home and see if space travel is something our species can achieve we have to start somewhere not sit around twiddling our thumbs and making up excuses for why it isn't worth it.

The moon isn't a hurdle to jump then move on. Bad analogy in my opinion. The 'been there done that attitude' of many people is what has contributed to our lack of continued visits to the moon. We still have tons to learn about the moon and to learn from the moon.
